As the suspension
flows along the screen plate, thin layers of water are being
sliced off by the screen bars and pass through the slots together
with fine particles.
SPECIALTY
A simple and effective
machine capable of separating fiber as small as 100 microns
in length from water suspension It is very compact
and has no moving pars and requires a minimized maintenance.
The unique screen plate is constructed of wedge bars forming
a bowed surface with horizontal slots between the bars. The normal slot width being 150 microns and the front
surface of the screen plate is polished. The flow to be screened
is fed through a nozzle, which distributes the flow tangentially
to the full screen width by means of an adjustable slice providing
optimum feeding velocity.
Cleaning of Screen
If under unusual
conditions they were plugged to plug up, they can easily be
cleaned with a water hose even during operation.
The water consumption
for screen cleaning is 120 L.P.M. (32 G.P.M.) per screen plate,
the required water pressure being 7.0 bar(100 psi)
The feed slice normally
has an opening of 2-4m/m (0.08-0.16'')
It is expected that screen is equipped
with an automatic operating cleaning device with a pneumatic
cylinder for quick opening and closing of the feed slice.
